摘要/Abstract

摘要：

丛枝菌根(arbuscular mycorrhiza, AM)真菌是一类专性共生多核生物, 至今尚未获得纯培养, 与植物根系共生后才能完成其生活史。该类真菌无性繁殖,具有独特的遗传特性, 属于真菌界球囊菌门(Glomeromycota), 共有200余种。研究发现AM真菌种群间以及种群内, 甚至单一孢子内都存在大量基因变异, 表明该类真菌具有丰富的遗传多样性。本文总结了近年来有关AM真菌遗传多样性方面的研究进展, 并讨论了存在的问题。

Abstract

Arbuscular mycorrhizal (AM) fungi are obligate symbiotic endophytes which have not been cultured in vitro. The life cycle of AM fungi can be completed only when the mycorrhiza forms between the fungi and plant roots. There are more than 200 genetically-diverse species of AM fungi belonging to Glomeromycota in the Kingdom Fungi. It is well documented that surprisingly high genetic variability exists between and within species, and even in a single spore of AM fungi. We summarize recent advances in the study of AM fungal diversity, discuss some related problems, and introduce present and future research trends.

Key words: arbuscular mycorrhizal fungi, genetic diversity, gene variance
